Wireless remote data
Technologies and sample systems that gather sensor data across distances, usually via radio links. This includes general telemetry and SCADA (supervisory control and data acquisition), especially for gathering data about wildlife, natural resources, and distributed energy systems.

FM radio from your PC: "PCI MAX 2005 is a computer card that will .. change your PC into a FM radio station. You will be able to play your audio files (CD, wav, MP3, real audio etc.) from your PC through radio waves directly to your household radio receiver in the next room, in the living room, across your yard, in whole block of flats....or for the entire village/small city. .. The included software (also available at the link below for a quick DL) lets you set the frequency and the output power.

gumstix: Nifty tiny processors that can run Linux, with bluetooth and adaptors for USB and other I/O.  10:12:25 AM  permalink  

More on the AMD PIC:  Cringely offers some info and suggested applications outside the developing world:  "the OS is Windows CE. It keeps user changes and personal settings on a separate disk partition so that the main OS partition can be updated at any time back to factory settings from a hidden 'factory reload' partition. It has no legacy interfaces at all (just VGA, RJ11 modem, AC'97 audio ports, and four USB 1.1 ports). It has no fan or even any passive ventilation. It has a 366 Mhz AMD Geode processor, 128-megs of SDRAM, and a 10-gig Seagate hard drive. It is ugly [but] cheap.  Think of the PIC as a cheaper, dumber Mac Mini. ..

in the ultra-low-end computer market right now as consumers are starting to use mobile phones to perform functions that might previously have been done with handheld computers like the iPaq. As a result, handheld sales are actually dropping, which in the PC market means the niche is already dead. .. The logical thing to do, it seems to me, is to split the niche into its two component parts -- mobile communication and cheap computing. Phones get the nod for mobility, but HP and Dell could easily pick up the cheap computing segment by selling many sub-varieties of PIC. It is ideal for home automation, for becoming a car video server to end drowning in Dora the Explorer DVDs, for acting as a home Internet gateway, for hosting the inevitable VoIP home PBX -- each a 100 million unit market, and each totally untapped by the big OEMs. .. Given a bit more effort on AMD's part, this little guy could be used to replace fading K-12 PCs all over America at prices that schools can actually afford. The power savings alone are such that an eight watt PIC will pay for itself in under two years. .. "

Cringely links to a page showing an Antiguan hacker's view of the PIC, and the AMD annoucement page that says that Linux will soon run on it.
